To all whom it may ero-neemt:

Beit known that I, CHARLES H. PHILLIPS,

a. citizen of the United States, residing at Maglewood, in the county of Middlesex and.

tate of Massachusetts, have invented certam new and useful Im rovements in; Flushing-Valves for Water-C osets and I do hereize and improve'iiushing valves of this type in order to make them more compact and certain in operation and to aord eter facility for dismantling and assembixig.

To these ends the present invention consists in the flushing valve hereinafter described and particularly defined in the claims.

In the accompanying drawing illustrating the preferred form of the invention, Fp'ure 1,

is a sectional elevation of the valve en Fie'. .2 is a transverse section showing the method of packing the opel-atico lover.

The illust-rated embodiment of the invention is describ'ed as followsz* The water enters through the service pipe Vt and passes through the shut off cock S into ipe P which discharges into the valve cha-miller C from which, when the valve V is open, the water flows to the outlet O. The

valve is Opened by a hund operating lev er L. The "alve body l consists of an inte-gral casting provided with a valve chamber C which contains the main valve and affords su port for the operating level' L and the pipe l which is connect-cd by a union 2 with the service pipe W' and contains a shut off cock S. The. valve V is mounted upon a valve stem 3 und provided upon its under side bv a fo ower 5 screw-threaded on the hub of the valve. The valve V is guided by idcs 6 -in the interior of the valve chamber. "alve V is provided with a central relief vulve 7 which is screwed on the stem 3. The valve. stem 3 is permitted to have u limited lungi tudinol movement through the valve V in order to secure the opening and closing of the relief valve 7. The aperture in the center of the valve V is lnrger than the valve stem 3 and the valve stem is provided with a plurality of Wings 8 which sup ort the valve thereon. The lower ends of t e wings 8 are provided with projections ada ted to enga. e the hub -on the under side o the valve The external diameter of this hub of the valve-V is larver than the external diameter of the circle mcludin the ends of the projections so that the ollower 5 may be unscrewed and removed.

The valve operatin lever L is rovided with an arm 9 inte a therewith w ch extends underneath t e bottom of the valve stem 3. When the lever L is raised the arm 9 engages the valve stem and lifts it, thereby opening the relief valve 7 and relieving the ressure on the upper side of the valve V.

he further upward movement of the lever L then lifts the main valve V and permits a large stream of water to ass through the valve to the apparatus to flushed. The upper end of the valve stem is provided with a piston l0 which loosely fits the piston chamber 11 formed in the cap 12 which is screw-threaded into an aperture in the upper end of the valve body. A cylinder head 13 embraces the iston stem below the pistou and is screiwt aded upon a reduced portion of the lower end of t e cap. The piston l0 does not fit the iston chamber 1l, but moves loosel and reely therein excepting so far as the ow of water from the one to the other side of the piston impedes its movements and it may, therefore, roperly termed a water check. Nhen t e lever L 1s ermitted to fall, the main vulve V being no onger supported by the valve stem 3, falls. Its downward movement under the iniluence of the fessure of the water thereon would natura y be nite rapid, so rapid in fact, as to cause the v ve to strike its seat with a severe blonT and the sudden closing of the valve f would cause a serious Water hammer owing g' to the sudden checking of the How of water l ment of the v ve V is however, prevented i by the piston 10 secured to the upper end of i the valve stem 3. The friction incident to i the passage of water from one to the other side of the piston 10 impedes the downward movement'of the valve and prevents it from closing ratplidly. It will be observed, however t at e valve V reaches its seat exertm a pull upon the valve stem 3 which is resiste by the piston l0. At the time of closing,

' with n aching ring 4 which is held in place i in the service ipe W. Such rapid move- 100 therefore, of the valve V the relief valve is still open and the liow of water into the service ipe is consequentl brought to n stop graduell From the tmle of closing of the main va ve V until the time of closing of the relief valve, the flow of water throu h the relief valve opening affords refill for t e apparatus to be flushed.

The means by which the hand lever Lls supported in the valve body and the means for packing the joint com rise a, useful fen.- ture of the invention. T e lever L is pro vided outside of the casing with en erm 14 secured thereto by means of a pin 15. A bushing 16 is exteriorly screw-threaded and adapted to be screwed into a hole in the side of an extension from the rear lower portion of the valve chamber. The bushinv 16 fits the enlarged end 17 of the lever L nucl efords a pivotal sup ort therefor. The hole 1n the bushing is en urged et its inner end to provide a. packing space 18. The arm 9 on the end of the lever L is provided with a hub which ts the enlarged opening in the inner end of the bushing 16. Between the hub and the end of the enlarged space in the bushing the packing is received. In order to maintain the lever in the proper position with relation to the bushing so as to compress the packing the end of the lever L is recessed and provided with a spring 19 against which the plunger 20 fitting the ring recess is lpressed by engagement with t eopposite vra 2l ofthe extension from the valve body. The lever is removed from the valve body by removing the pin l5 and sliding the arm 14 back on the lever.

turned so us'to remove the arm 9 througgi the and plunger 20 bein put in place the arm 9 of the lever L is hoo 'ed thro ugh the opening of the valve body and the lever L is pushed far enough in to cause the lunger 20 to cornpress the spring 19 some` et then the bushlng 16 is screwed into the valve bodv wbereby the lever L is securely fixed in place, the

packing 18 is compressed to prevent the escape of water an( the lever L is niorded 5 a good support in the bushing. The arm 14 is then sh into position und pinned fast to the lever b the in 15.

The gra. ual e osing` of the main valve Y has been described as being secured by the impediment to its movement imposed by the resistance to movement of thc pistou l0 in the valve chamber 11. This resistance is however, not the principal resistance to the closing of the valve 'V but the subordinate or secondary Ineens for this purpose which it has sometimes been found ludvuntopgame to Then the g bushing 16, which is provided -with s hexg agonal surface, is unserewed and slid buck on the lever L whereupon the lever muy be pressures. The rincipel means for preventmg the sudden c osing of the water valve V is the air cheek A comprising the piston 22 mounted in the air c liuder 23 projected downwardly from and integral with the shut oil valve S. The cup leather 24 is secured to the (piston 22 by means of the screw 25 which hol s the piston 22 und follower 26 tovether. l The head of the screw 25 is provided with two eers und e. link 27 is secured thereto b means of a pin 28. The lower end of the lin 27 is pinned to the end of the arm 14. An air outlet from this cylinder 23 is provided which extends up through the shut olf valve and n. regulating screv: 29 havin a tapered end adapted to be adjusted in t e tapered seat in the lower end of the outlet passage affords provision for regulating the rute of out-flor.r of nir from the cylinder 23. The screw 29 is grooved at its upper end where it engages the threaded end of the air passage so as to afford provision for egress of air but the regulation of the outflow of airis secured by means of the tu. ered end of the screw closing more or less t e corresponding seat iu the sir outlet passa e. When the lever L is raised the cup lent-1er 24 ermits the free movement of the piston 22 ownward in the. cylinder 23 but when the lever L falls its movement is retarded by the slow escape of :nir from the cir outlet passage iu the shut off vulve. The lever L is Weighted at its end so 3 as to afford means additional to the flow of g the Water for pressing the piston 22 upward in the cylinder 23. The Weight ofthe lever L together n'itn the friction of the. water against the valve V tends to force the ai r out of the nireheck. The shut oil' valve S consists of n perforated tapered plug received in u tapered hole in the pipe P. A nut 30 und Washer 3l alim-d means for securing the shut oil vulve in position in the pipe P. This valve also obviouslv affords menus for regulating the rale of tion' of the water through i the. apparatus by opening or closing this i vulve more or less.

When it is desired t-o dismantle the valve, the plug of the shut off valve S is turned to A shut olf the supply. It will be observed that this does not. sr'ect the air check es it is concentric with the shut ofi' valve. Then the` cap 12 is unseren-ed and when it is lifted oli it i carries with it the valve stem and valve. i The packing 4 ma f then he replaced and the parts restored Wit. out trouble.

When it is desired to flush the apparatus with which the. valve is connected the hund lever is raised and the relief valve is opened lli-st, then the main valve is opened and es l this is taking luce the piston 22 is pulled dou-n in the cy inder 23 thereby permitting air to oss by the piston 22 into the chu-Inbev thereaiovc. The piston mounted on the vulve stem nud working; in the chamber 1l employ in valves opera-ting under high water {ts such chnmbers so loosely that the movejustment of the screw 29.

ment of the piston inthe chamber .offers no substantial impedimentI to the opening of the valve. When the valve has been opened to its full extent the lever'L may be pernntted to dro and the tendency of the water to close t e main valve V as well as the weight -of the lever will gradually force the main valve down incidentally expellinv the air from the space above the piston 22 in the cylindex- 23 through the air escape passage of the shut olf valve S. The rate of closin of the valve is conveniently regulated by t ie ad- By turning the screw 29 in one or the other direction the duration of the o n pen'od of the valve may be regulated witliwprecision to cause the discharge of the proper quantity of water under any given head.

One feature of the invention resides in the combination of the water valve having a relief opening with a separate air check. This is of importance because of the facility of assemhling and dismantling. In the present construction it `vill be observed the Water valve may be taken out without disturbing the air valve.

Another feature of the invention resides in providin check cy 'nden This feature contributes to compactness and strength.

Another feature of the invention consistsin the arrangement of the air check so that the tendency of the water valve to close is resistcd by the compression of the air therein.

This is of advantage as it secures a const-ruction incapable of adventitioiis deiangenient by the user, as the rate of closing of the valve air escape passage.

Other features of the invention are particularly defined in the claims.
